Analog Devices Inc. ADRF5024SCCZ-EPR7

Overview

ADRF5024SCCZ-EPR7 from Analog Devices is a reflective silicon SPDT RF switch operating from 100 MHz to 44 GHz, delivering 1.7 dB typical insertion loss at 44 GHz with impedance match and >35 dB isolation. It supports hot switching at 27 dBm RF input power and features CMOS/LVTTL-compatible control with ±3.3 V dual supplies. Used in 5G mmWave infrastructure and military radar front-ends.

For engineers reviewing the ADRF5024SCCZ-EPR7 datasheet, ADRF5024SCCZ-EPR7 pinout, ADRF5024SCCZ-EPR7 application, or ADRF5024SCCZ-EPR7 equivalent, key selection criteria include ultrawideband insertion loss vs. frequency, RF power handling under hot-switching conditions, isolation between RF paths, settling time (17 ns to 0.1 dB), and −55°C to +105°C military-grade thermal operation.

Technical Context

The ADRF5024SCCZ-EPR7 implements a reflective SPDT topology using silicon process technology, enabling broadband RF path selection without external bias tees. Its RFC–RF1/RF2 architecture maintains 50 Ω ac-coupled matching on all RF ports and supports dc-coupled operation when RF line potential equals 0 V.

Control logic uses dual-supply CMOS/LVTTL-compatible inputs (0 V / 3.3 V) with ultra-low quiescent current (14 µA on VDD, 120 µA on VSS). Switching performance is characterized by 10 ns on/off time (90% RF output) and 17 ns RF settling to 0.1 dB final value, critical for fast-hopping systems.

FAQ

What is the maximum RF input power rating for ADRF5024SCCZ-EPR7 during hot switching?

The ADRF5024SCCZ-EPR7 supports 27 dBm RF input power during hot switching on the RFC port and 26 dBm on RF1/RF2 ports at TCASE = 85°C. At +105°C case temperature, this degrades by 3 dB due to thermal derating. The device's reflective architecture and silicon process enable robust hot-switching without latch-up or permanent degradation when operated within absolute maximum ratings.

Does ADRF5024SCCZ-EPR7 require external dc blocking capacitors on its RF ports?

No, ADRF5024SCCZ-EPR7 does not require external dc blocking capacitors on RFC, RF1, or RF2 when the RF line potential equals 0 V dc, as all three ports are dc-coupled to ground. This simplifies PCB layout and preserves broadband performance. If dc bias is present on the RF line, appropriate blocking capacitors must be added per the interface schematics in the datasheet.

What is the significance of the "EPR7" suffix in ADRF5024SCCZ-EPR7?

The "EPR7" suffix denotes tape-and-reel packaging with 7-inch reels, intended for automated SMT assembly. It shares identical electrical, thermal, and mechanical specifications with ADRF5024SCCZ-EP, including −55°C to +105°C operation, AQEC qualification, and CC-12-3 LGA package. The marking code "S4" is laser-etched on the top surface for traceability.

How does the ADRF5024SCCZ-EPR7 achieve 50 Ω impedance matching across 100 MHz to 44 GHz?

The ADRF5024SCCZ-EPR7 achieves broadband 50 Ω matching through monolithic silicon design with integrated transmission line structures and optimized internal layout. RF ports are ac-matched to 50 Ω and dc-coupled to ground, minimizing parasitic discontinuities. Optimal performance requires proper PCB implementation: 50 Ω microstrip lines, ground-signal-ground probe pads, and tight coupling to the EPAD - as validated on the probe matrix evaluation board.

Can ADRF5024SCCZ-EPR7 operate with only a +3.3 V supply, or is the −3.3 V rail mandatory?

The −3.3 V supply (VSS) is mandatory for ADRF5024SCCZ-EPR7 operation. The device uses complementary control circuitry requiring both +3.3 V (VDD) and −3.3 V (VSS) rails to achieve full logic swing and specified switching performance. Operating without VSS violates absolute maximum ratings and will result in functional failure or damage. Supply sequencing - VSS before VDD - is recommended per the datasheet.
